Cats/Mature size


I have an almost 5 month old male mix breed kitten. He was neutered at 4 months. He weighs about 6 pounds now. I was wondering if you could tell me when he should stop growing and what the average weight is for a male cat, assuming he's fed a balanced species appropriate diet.


Depending on the body type, it could take anywhere from 18 months to 5 years to become fully mature.  The slinkier body types (like Siamese or Abyssinians take about 18 months, the more robust body types like American Shorthairs or Maine Coons can take anywhere form 3 to five years. So, it is difficult to be precise. One guide is often the size of his feet.  Cats often grow into their feet, but this is usually a very rough estimate.

Male cats can be anywhere from 8 pounds to 25 pounds depending on the body structure.

So, I really cannot give you a precise answer.

I am sorry I could not be of more help.

Best regards... Norm.

I can answer most non-veterinary questions about cats. My particular expertise is pedigree cats, breeding and showing. However, I am versed in feline behavior, cat breeds and their characteristics, general feline husbandry, and the like.

I have been breeding pedigreed cats since 1971 and have been exhibiting pedigreed cats in shows since 1970. I obtained my first pedigreed cat in 1970 and have never looked back. In 1971, I obtained my first Abyssinian which has become my primary breed. In addition, I have bred Manx and Persians. Currently, besides the Abyssinians, I am also breeding Maine Coons.
